Project description
PerfLens 🚀
PerfLens (性能放大镜) 是一个极简的 Python 库。它提供了一个优雅的装饰器，帮助你瞬间洞察函数的执行耗时和内存峰值占用。
为什么选择 PerfLens？
零依赖：只使用 Python 标准库，不污染你的环境。
极简 API：只需一行 @measure。
直观输出：直接在终端打印美观的性能报告。
快速开始
将 perflens.py 放入你的项目中，然后像这样使用：
from perflens import measure
@measure def process_data(): # 模拟一个吃内存和耗时的操作 data = [x**2 for x in range(1000000)] return sum(data)
process_data()
输出示例：
🚀 [PerfLens] 函数 'process_data' 执行完毕: ⏱️ 耗时: 0.1234 秒 💾 峰值内存: 38.5123 MB
